I was talking to a friend the other day and she lit up a cigarette. I said "I guess you didn't get the memo. Smoking is still bad for you."

She said, "I know. I know. But I asked my doctor, and he said, 'Anything in moderation is OK.'"

What? Yeah, I can see getting drunk once in a while, or consuming an entire pint of Ben and Jerry's at one sitting being OK, but smoking in moderation? I don't know about that one.

According to the ACSH (American Council on Science and Health), cigarette smoking is a lot different from let's say, eating candy. People can consume a king size Snickers bar here and there without hurting themselves. There is no such thing as "smoking in moderation." Any amount of smoking is bad for you.

Fit's Tip: Looking to kick the habit? Call 1-800-QUIT-NOW or go to www.smokefree.gov for info. Quitting smoking is way too hard to do it alone, so think about joining a support group.
